Cards Term the function of the cerebellum Definition monitor both sensory and motor, combines with vestibular-creates smooth and coordinated movements Term the development of the cerebellum Definition in the rostral portion of the metenceph, rhombic lip forms the cerebellum Term the worm like band along the midline Definition vermis Term the ridge of tissue on the cerebellum Definition folia Term the grooves on the surface Definition sulci Term where is the gray matter located Definition on the surface (cortical), embedded in the white (subcortical) Term the white matter deep to the surface that is named for the orientation of white matter Definition arber vetae Term the lobe at the front of the cerebellum Definition the rostral lobe Term the lobes on the dorsal side Definition the caudal lobe Term the lob along the ventral side, has tufts of grey matter on each lateral side Definition floculonodular lobe Term the very deep groove that separates the rostral lobe from the caudal lobe Definition primary fissure Term the very deep groove that seperates floculonodular lobe from the caudal Definition caudolateral fissure Term the bilateral subcortical nuclei Definition cerebellar nuclei Term the cerebellar nuclei closest to the midline Definition fastigial nuclei Term the cerebellar nuclei in the middle Definition interpositus nuclei Term the cerebellar nuclei that is farthest from the midline Definition the dentate nuclei Term the oldest developmental stage Definition archicerebellum (floculonodular lobe) Term the middle developmental stage Definition paleocerebellum (rostral lobe) Term the youngest developmental stage Definition Neocerebellum (caudal lobe) Term the layer of the cerebellum which synapses and processes Definition molecular layer Term the layer with operative cells, monitors the info, lined up through the layer Definition purkinje layer Term the inner most layer Definition the granular layer Term the fiber type from the olivary complex the the molecular layer to purkinje dentrites, the extrapyramydal relay system Definition the climbing fibers Term fibers from brainstem and cord to the granule cells, from motor fibers of the paramydal or SC or vestibular system Definition Mossy fibers Term the fibers from the granule cells to the purkinje cells, activates purkinje and sends into back to deep cerebellar nuclei Definition parallel fibers Term where the proprioceptive info enters Definition spinocerebellar/vestibulocerebellar tracts Term where the extraparamydal motor system feeds, forms climbing fibers in the cerebellum Definition the olivocerebellar tract Term where the pyramidal motor system enters, contributes to the mossy fibers Definition the pontocerebellar tract Term one of the deep cerebellar nuclei that go to the vestibular nuclei Definition fastigial nucleus Term the efferent fibers that go to the red nucleus and form the rubrospinal tracts Definition interpositus nucleus Term the numerous projections that go to the red nucleus, thalamus, and basal ganglia Definition dentate nucleus Term archicerebellum Definition the vestibulocerebellum (lesion causes disturbance in balance/equilibrium) Term paleocerebellum Definition spinocerebellum (reglate posture, tone) Term neocerebellum Definition pontocerebellum (regulate highly skilled movement) Term signs related to cerebellar lesions Definition inability to regulate movement-dismetria, may overshoot stride, nystagmus
